Application filed June 8, 1906. Serial No. 320,874.

To all whom it may concern:

Be it known that we, JOHN R. GRIFFITH and LESLIE G. GosrEn, citizens ofthe United States, residing at Independence, in the county of Montgomeryand State of Kansas, have invented a new and useful Well-DrillingMachine, of which the following is a specification.

This invention relates to well drilling apparatus; and it has particularreference to that class of drilling machines which are mounted uponsuitable running gear so as to be capable of being conveniently transported from one place to another.

One of the principal objects of the present inven tion is to provide amachine of novel and improved construction which may be usedinterchangeably for operating drilling mechanism through the medium of awalking beam, or by spudding mechanism, or whereby, when desired, arotary drill may be operated; means being likewise provided foroperating the sand pump, and likewise for hoisting or otherwisemanipulating the well casing by means which are independent of thedrilling mechanism, so that the drill rope does not require to berethreaded or rearranged when the casing is to be manipulated.

Further objects of the invention are to simplify and improve the generalconstruction and operation of the machine.

With these and other ends in view, which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of parts,which will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention; it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention may be made, when desired.

In the drawings, Figure 1 is a side elevation of a drilling machineconstructed in accordance with the principles of the invention. Fig. 2is a top plan view of the same. Fig. 3 is a vertical transversesectional view taken on the plane indicated by the line 3-3 in Fig. 2through the main shaft of the machine. Fig. 4 is a detail view, inelevation, of a portion of the main band wheel., Fig. 5 is a perspectiveview of the clutch betweeuthe main shaft and bull wheel, the members ofthe clutch being shown disassembled.

Corresponding parts in the several figures are indicated throughout bysimilar characters of reference.

The frame F of the improved machine is supported upon running gearincluding the front and hind wheels 1, 2. The main shaft 3, which issupported for rotation in suitable bearings upon the side members of theframe, carries the drum or reel 4 having at one end thebull wheel 5 andat the other end a flange G, the latter being bolted or otherwisesuitably secured upon a collar '7 which is formed upon the body of thedrum. The latter is provided at the opposite end with a collar 8 andwith an annular loose ring or flange 9 between which the bull wheel 10is secured, as by means of clamping bolts 1]. At the ends of the drumare recesses, as 12, affording seats for an lifricrion rollers 13 whichare retained in position by means of collars 14.

One end of the drum 4 which extends beyond the bull wheel 10 has aclutch member 15 adapted to cooperate with a clutch member 16 formedupon a hub 17 that is keyed upon and in slidable engagement with themain shalt 3; said hub carrying also a sprocket wheel 18. The hub 17 hasan annular groove 19 engaged by a shipping lever 20 which is under thecontrol of the operator who, at will, may engage the clutch members 16and 15 to thereby lock the drum 4- upon the shaft 3 for rotation withthe latter.

The main shaft 3 carries at one end, which extends beyond one side ofthe frame, a belt wheel or band wheel 21. which is clamped between hubmembers or flanges 22 and 23 that are bolted together through the bodyof the band wheel, which latter is secured upon the shaft by means of akey or spline 24f engaging the hub members. The outer hub member 23 ismade up of two segments connected with each other by transverse clampingbolts 25 whereby the key or spline 24 is clamped very securely inposition. By loosening the bolts 25, the key or spline 24 may bewithdrawn and the band wheel may then be removed from the main shaft;this being a matter of great convenience when a machine is tobetransported from one place to another, especially over rough ormountainous roads. "he opposite end of the main shaft 3 carries a crank26 having a wrist pin 27 adapted to be connected by means of a pitman 28with the walking beam 29 which is supported upon the Samson post 30, thelatter being preferably com rosed of two beams converging upwardly inapproximate A-shape, so to provide an extended bearing surface andthereby relieving the frame of the machine from ulniecessary strain.

A flexible brake band 3]. encircles the bull wheel; one end of saidbrake band being connected in the usual manner with a crank 32, which isconnected by a link 33 with another crank 34. capable of beingmanipulated by a lever 35 at the front end of the machine, where it maybe conveniently controlled by the operator.

A shaft 36 is supported in suitable bearings, parallel to the shaft 3,and is driven therefrom by the sprocket l8, link belt 41 and sprocket40, said shaft 36 carrying a clutch member 37 which is splincd on thesame, so as to be slidable thereon and rotatable therewith; said clutchmember being controlled by the operator by means of a shipping lever 38.The clutch member is l which one end of the sand reel shaft isjournaled, is

adapted for engagement with a drum 42 which is rotatable upon the shaft36 and which carries at one end a brake wheel 43 clamped between theflanges 14 and 45 and encircled by a brake band 46, one end of which isconnected with a crank 47 operable by a lever 48. The shaft 36 carriesat one end a sprocket wheel 49 adapted to be connected by a link belt 50with so-called rotary apparatus constituting a rotary drilling outfit atthe well opening to which power may be in this manner transmitted, whendesired. The shaft 36 carries at its opposite end a crank 51 having awrist pin 52 upon which a spudding wheel 53 is mounted for rotation; thesaid spudding wheel being in alinement with a guide pulley 54 that issuitably supported upon the frame of the machine for the purpose ofguiding the rope to the spudding wheel from the drum 4:, and preventinginjury to the rope by frictional contact with the frame of the machine.

The drum 42 upon the shaft 36 is adapted to carry a flexible element'forraising and lowering the casing, which operation may thus be performedindependently of the drill rope, which in practice is wound upon thedrum 4. A separate drum and hoisting element for manipulating the casingis always a valuable acquisition either to a standard rig or a drillingmachine, and it is an absolute necessity when a rotary drilling outfit;is used.

A shaft 55 supported for rotation in bearings in rear of the main shaft3 carries the sand reel 56, and said shalt also carries a frictionpulley 57 adapted for engagement with the band wheel 21 to be therebydriven. One of the bearings of the shaft 55 is in a lever 58, wherebythe shaft may be slightly rocked, as required, to place the frictionpulley 57 into or out of engagement with the face of the band wheel; thelever 58 being connected by a link rod 59 with an operating lever 60 atthe front end of the machine.

The band wheel 2]. may be driven from any suitable source of power; whenthe machine is a large one, an independent motor will preferably beprovided; if the machine, however, is not of great size, a motor, as M,may be supported upon the frame F; the main shaft (31 of such motorbeing provided with a pulley (32 adapted to be connected with the bandwheel 21 by means of a driving belt or band.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood by those skilled in the art to which it appertains.The main shaft 3 may be operated independently of the drum 4, but thelatter may be locked securely upon the main shaft by means of the clutchupon the hub 17. Motion is transmitted from the hub 17 and the sprocketwheel 18 upon the latter to the sprocket wheel 40, which rotates theshaft 36. By placing the clutch 37 in engagement with the hub of thedrum 42, motion is transmitted to the latter.

The entire mechanism of the improved machine is simple in constructionand may be readily controlled by the operator who is stationed at thefront end of the machine within convenient reach of the lovers wherebythe parts of the mechanism are controlled.

The operating lever 58, which provides the bearing in preferablycomposed of two separate parts or members 58 spaced apart by one or morethin washer plates, as 59; the members 58 being connected together onopposite sides of the plates by bolts 60, one of which is an eye boltthat serves to form a connection with the link rod 55). lly thisconstruction, wear of the sand reel shaft in its bearing may becompensated for by occasionally removing one of the washer plates, thusenabling the members 58 composed of the lever to be moved together so asto reduce the size of the aperture that constitutes the bearing for thesand reel shaft.
